Whaats a brony ?
A brony is a person who likes mlp. (my little pony) And typically specifically the fourth generation of it which is sub titled Friendship Is Magic.
Kind of started off in 2010 when the show was kicked off again when the new (at the time)) HUB channel came to be. And it acquired a fan base online (I think mostly on 4chan) and became popular there until people hated on them and there was fighting. Then ponies were banned from 4chan so the bronies spread around the internet.
But basically, people who like mlp.
which is really broad.
and there are different kinds of bronies too.
(like people who have a "twisted like" for the ponies have their own name: cloppers.)
some females prefer to call themselves pegasisters
and then there is the regular brony
the casuals are also called bronies
and then there are the bronies that dont want to be called bronies because cloppers call themselves bronies and then they dont want anything to do with that so they avoid it and avoid being called broneis
its weird
but whatever
